will be later-explained, so that the clutch teeth 24 will engage clutch teeth 26 on a member 21 carried on the driven shaft 28-.

The member 2'! is held to the shaft 23 by splines and also by a nut 29 and lock nut 30, both of which engage the screw threads on the end of the shaft 28. It will be noted that the lock nut 30 has a rounded end to act as a stop member for the flange 23 when it is moved into driving engagement with the member 2].. t L 7 Mounted on 'the sleeve I8, is an annular abutment 3|, thesame beingheId in place by'screws 32, each of which engages or positions a ball.

power from the drive shaft 9 is transmitted to the driven member 21 and driven shaft 28.

When it is desired to shift back to the position of Figure 3, the shaft bar 52 is operated so that the ring 50 engages the rods 45 which will move the racks 42 back to the position shown in Figure 3. Likewise, the pinion 3'! and rod 34 are moved back to this position, where it will be noted that the center line of the pin 34, when passingthrough its pivotal center, .will pass below the axis of the pinion 31, thereby providing an efiective locking actionbetween the pinion and its rack and holding the parts securely in 33 located in a seat in the sleeve l8. As shown in Figure 3, the screw 32 ma beintwoiparts:

so that the inner part is locked in position by the outer part. I prefer this type of abutment to one that is fixed to the sleeve asit willhave a slight movement to give freedom of action to a 7 pair of pins 3 5, each of which is pivotally mounted at .35 to its. projection 36 forming partuof. its
